What are WebP and ICO files?
WebP (.webp)
WebP is a modern image format by Google that makes files 25–35% smaller than JPG or PNG at similar quality. It supports transparency and animation, and is used heavily by websites — which is why images saved from the web often end up as .webp.
ICO (.ico)
ICO is the icon format used by Windows and by website favicons. One ICO file can hold several sizes (16×16 to 256×256) so the right one is shown everywhere.
Tips for the best ICO results
- Use a square source image of at least 256×256 px. The ICO file will contain 16, 32, 48, 64, 128 and 256 px versions for favicons and Windows.
- Bookmark this page or install the app to convert WebP files offline next time.
Private by design: how this converter works
Unlike typical online converters that upload your file to a remote server, this WebP to ICO converter processes everything on your own device using the HTML5 Canvas API and native image decoders built into your browser. Your file is read into browser memory, converted, and offered back as a download — it is never sent to us.
- No upload wait — conversion starts instantly, even on slow mobile data.
- Private — safe for NID copies, certificates, bank statements and personal photos.
- No limits — no daily quota, no queue and no watermark.
- Offline-ready — once loaded, many tools keep working without internet.
